State of Missouri; have invented certain new and useful Improvements in ,Car-Controlling Apparatus and I do hereby declare the following to be a full; clear, and exact description of the invention, such as'will en'- able others skilled in the art towhich it appertains to make and use the same."

This invention relates to new and useful improvements in car controlling apparatus,

andh'as for its principal object to provide a device which will simultaneously cut off the 1 power and apply the brakes to a motor car by operating'a single foot pedah Another object of the invention is to .provide a device which will also drop a trip member and permit the sand in the box of the car to fall upon increase the friction of the wheels.

A further object of the invention is to provide a device which is air operated and which will return to its normal running position .atthe desire of the user.

Still another object of. the invention isto provide a novel means :for controlling the flow of current to the motor which insures the erfect-contact at all times.

ith these and other objects in view the invention consists in'the novel combination and arrangement of parts which will be fully set forth in the following tion and accompanying drawings, in which,-

Figure 1 is .a top plan view partly in section of a controlling mechanism constructed in accordance with this invention and sho w ing the sameready. to be applied to a car of the usual construction, Fig. 2 is a view illustrating the device as it would appear. when attached to the car, Fig. 3 is a wiring diagram illustrating the circuit controlling means, Fig. 4 is an enlarged fragmentary view of Fig. 1 showing the'switch, and Fig.

5 is an enlarged detail sectional view showingathe controlling pedal.

.eferring now to he: drawings by charactors 'of reference, the numeral 1 desi nates. as an entirety the body of the car whic rests on the usual frame 2. This frame carries the usual journal boxesfi inwhich the axle y p V I I forward end 11 ,ofthe fraine Q and slidable i is journaled. Secured to the axles inthe usual manner are the wheels 5 -which are connected to the motor 1n any suitable way and are arranged to be driven thereby. The

I

Slida'ble vertically in the forward end- 11 of the frame isthe plunger designated genthe numeral 24 2 which comprises 7 25 which is slidable iii the frame 26. This frame 26 is connected t'o'the frame 9-at its forward end andsupp'orts the plan ger mechanism. A; suitable aperture 28; is formed'in the plunger 25 near its-upper end and is designed to per'mitfthe"forward end of the bar 21 to'pass therethrcugh.fiecured .-to the lower end of the slide 25' is-the tubu lar member\27 which is designed to slide on the Stem29 Whiehis carried by the'lower y end of the frame. An upwardly extending stem 30 is formed on. the upper "end-of the,

slide 25 and this stemlterininates inthefoot pedal 31 which is disposedijabove platforn iof thecar;

A pair of cylinders; 32. or

efsecurjii'tdthe in these cylinders: rethe pistons 33 to 'w-h ich the piston rods 34; ares'ecurefd, Tihesefpiston rods are fastened in bars centrally'of the side 'bafs is v slidable. This piston is provided with the usual piston ring 14 and carriesthe piston rod any suitable manon which the trolley Wheel 58 is "Tun. Thistrolley wheel is secured to, the

ner at their opposite terminals to the bar 16 and are arranged to act in a directlonoppo site to the action of the piston rod 15 hereinhefore mentioned.

The end of the bar. 16 opposite the angular extension 18 is connected as at 35 to the sliding bar 36. These two bars are insulated from each other as at 37 and the sliding bar is slidably mounted in the guide bars 38 which are insulated as at 39 from the frame 9. These guides are also insulated spaced from the guide 40 and are provided c I with the binding post 43,

which is arranged to energize the plate 44, which plate is pro- Vided with the lug 45 around which the spring 46 is coiled. This spring 46 is arranged to exert pressure against the plate and fore the same toward the lug 47 and against the end of the contact bar 36 when the same is in its normal position. It will thus be seen'that a device is provided which will throw in or throw out an electrical circuit according to the position of the contact bar 36 and arm 16';

Secured intermediate the ends of the bar 21 is the clamp member 49, which clamp member is arranged to be removably secured to the bar and support the rearward extension 48, which is slidable through the bracket 50. This arm 48 terminates in the downwardly extending member '51 which is designed to engage the upper bar 52 of the trip, fender designated generally by the numeral 53. This trip fender is pivoted as at 54 and the horizontal portion 55 thereof is arranged to be lowered when the arm 48 slides forwardly. This trip fender is normally held upwardly when the bar 16 is in the rearmost position as shown in Fig. 1, and this position is also clearly illustrated inFigL2.

In wiring thedevice in order to cut out the electrical circuit, theusual trolley wire designated by the numeral 57,- is provided arranged to usual trolley po1e59 which is connected at 60 to the wire 61 which carries the circuit;

current. i then to the binding post 43.- -The I asses from the binding post 43 through the bar 36 and the binding post 41 into the wire 62, from whence it passes into the controller designated generally by the n moral 63, and

thence out through the wire 64 to the motor 65, from whence the same. asses through thewir'e 66 to the ground des gn ted by the numeral 67. It-will thus be. n that an effective cut-out for the power supply is provided which will be operated upon moveconnected at 69 to, the wire 61 at a post 43, and this in e 68 is connected to 67 through the bar 16 forwardly,

' maniac merit. of the bar 16 in a forward 1. i In order to prevent the lighting system the car from being affected, the wire 68 intermediate the point 60 and the hindin lamp jacket 70, the opposite terminal or which is connected to the wire 71. wire/71 "is provided intermediate its with the resistance means designated by numeral 72 and the switch designated y the numeral 73. The opposite end of the wire is connected. as at 74 to the ground wire 66,rand it will thus seen that a complete short circuit througn the lighting system is provided which is not at all afiected by the operation of the motor. In order that the operation of the device may be positive, the air from the air bralze system is used and passes from the reservoir 75 through the valve76 into the pipe 77 and thence through the pipe 7 8 and check valve 79, into the cylinder 12 and behind the piston 13. A suitable blow-oil check valve 80 is providedto prevent the pressure within a the cylinder 12 from becoming excessive, and when the operator presses his foot upon the'pedal 31 it Will be apparent that the member24 will descend until the aperture 28 comes into alinement with the end of the rod or bar 21. This will permit the bar to slide forward under the influence of the air pressure in the cylinder 12 against the ton 13 until the limit of power has been reached, which will simultaneously force the 1 39 thereby allowing the sand carried in the box 20, to pass through the pipes .and on to the track. Simultaneously with this movement the power is cut 06 bv the bar 36disengaging-the plate 44 and when the piston has rearhed its limit of travel the outlet. pipe 81 will be uncovered which will permit the airto pass through the check valve 82 and into the pipe 83, from whence it will pass into the brake cylinders of the car and thus apply the brakes. The air passing into'the cylinder 12 will also pass into the pipe 84 and thence forwardly through the valve 85 to the indicator designated by the numeral 86, thereby plainly indicating to the controller of the vehicle the amount of air pressure within the cylinder. After the car has been brought to *a stop the lever 87 of the valve 85 is thrown in such a position as to open the valve and permit the air within the cylinder to flow then the trip member 53 is raised to the po- I tor car, of a frame secured beneath the car,

. through the electric motor 'inders .being in constant qwith an air reservoir, a bar frame, a piston within the cylinder,said piston being connected to the bar and ar.

an pressurein the cylinder,

permit the same to slide sition illustrated in Fig. 2.

It will thus be seen that a particularly simple and eifective device is provided which may be controlled from a and which will efiectively brin a gcar to a standstill in a relativelyshort gist ince.
